Be it known that I, WVILLIAM F. DimRioH-- WILLIAM' F. DIETRICHSON, or ST. Louis,

MISSOURI, ASSIGNOR T0 AMERICAN-CA AND FOUNDRY COMPANY, or' ST. L oUIs, MISSOURI, A CORPORATION or NEW soN, a subject of the King of Norway, residing at the city of St. Louis, State of Mis souri, have invented a certain new and useful Improvement in Metallic Ends for Rail- Way-Cars, of which the following is a full, clear, and eXact description, such aswill enable I'others Skilled in the vart towhich it appertains to make and use the same, reference being had to the accompanying draw- .ings,.forming part of this speciicatioii.

This invention relates generally to. rai-lw'ay car structures, and more specifically to an improvedA construction for the ends of freight cars. f

As is well known in practice, the ends of freight cars are subjected to destructive influences, Vsuch as the thrusts of l the cargo under its inertia when the car :is .suddenly started or stopped, and hence the provision y of a very strong end structureoriginally,

and also one which may be readily repaired v and thev parts thereofreplaced with facility,

are factors of great importance in car build- 111g- In recent practice, it has becomeconimon to. form .the car endgf sheet metal, suitablyv reinforced to give it the necessary stiffness and stability, and subdivided into sections which are susceptible of individual replacement in caseof damage.

Different cars, of course, are designed to carry different loads, and an end construction which might be sufficiently strong for one car, would not'be sufficiently strong forv a car designed for a" heavier load. There-` fore, in order tosecure the greatest economy,

it naturally followsthat ends should be constructed for each of the severalgdilferent load-capacity cars. l.I-Iowever, in view of the great variation in load-capacity of cars, it is not practical or economical to construct an end for each class of cars. The basis of this statement is obvious when it is remembered thatthese ends are carried as supply parts in repair-shops, in'which shops cars of every size and description are repaired. l It is the purpose of my invention to provide an end construction which is. designedl to meet allrequirements and variations asI `to strength in the'mostpractical and economical fashion. This I do byproviding an end structure wherein all the major parts, such-as those requiring special shaping, are

uniform for all applications of the end, but

which also includesone or more load carrying elements'wliich may be varied at will to suit the particular circumstance, and which, because of their intrinsic nature,l may be readily shaped in any'repair shop. In' this fasliion, I am enabled toy provide a structure capable of wide variety of applications, yet

containing for the most part uniform parts;

My invention also contemplates improvement in the manner in which metallic ends may be secured tothe car structure, th'e purpose being to provide a more substantial and stable connection between the end structure and the framing members ofthe car. I

With these, and other objectsin view, the which will be pointed out hereinafter or obviolis upon an understanding of the structure, I have devised a metallic car end structure one lform of which, for the purpose'of illustration, 'is disclosed in the accompanying` drawings in which:

igure 1 is a front elevation;

Fig. l2 is la horizontal section substantially I on line 2 2 of Fig. 1;

' ing its lateraledges turned rearwardly to provide flanges 2 and its lower margin i ,flanged outwardly in L-for'm to form a yweb tand the flange 5. The web is widest across the central portion of the panel and tapers in width gradually toward the side margins. As a consequence of forming the web in this fashion, the flange 5-is narrowest across the central portion of the panel, and

increases in width toward theside margins. Suitablecorrugations G are preferably provided in the4 panell so as to give it the necessary stiffness and stability to resist bending moments duedto'local horizontal'v Associated with theiupper'panel l lower panel 7 in ther form of a flat sheet riveted at its upper margin to the panel 1l adjacent the .web Llby rivets 8. The lower margin of the panel 7 is anged rearwardly and connected to the end sill covervplate 9 by the rivets 10.v On the outer side of the lower panel 7 are riveted one or more vvertical reinforcing members 11 which Vare their' lower ends these vertical reinforcing rearwardly.

so f

memberspass through apertures in the end sill cover plate and are riveted to the end sill 12 by the rivets 14. At the lateral inar- `gins of the lower panel 7 angle members 15 of any suitable commercial form are 'riveted, their lower extremities being. passed through apertures in the coverplate and 4being riveted to the extremities of the end sill, and their free flanges 1.5"l extending The size and contour of the web l and flange are such as to embrace the vertical reinforcing members 11 and the angles l5, to Iwhich the flange is secured by rivets. This construction'at the lower' edge of panel 1 provides a truss member extend-l ing completely 4across the end structure substantially atfits girth line, and providing a very stiff and stable reinforcement across the zone mostsubje'ct to cargo thrusts. In this truss member, the upper portion of the lower panel forms the compression member. with respect to cargo' thrusts, the flange 5. forms the tension member, andthe web 4 and reinforcing members 11 form strutsbetween the tension. and compression members.

The parts so far described may be termed the uniform members ofthe end .structure, by which I mean to indicate that these mem` bers may be employed in end structures del signed for any of a wide variety of maxi-g mum loads. As the variable element of my structure, which variable element, as indicated above," is designed tobe Varied to meet the requirements of the particular car, I employ an angle member l16. This is an ordinary commercial or pressed shape which is commonly kept in stock at any repair ings, suchy 'as the rivets 16. This variable,

shop, as it is susceptible of awide variety` This member is inserted between the upper extremities of theA vertical reinforcing members 11 and the flange 5 and web 4 of the upper section.V It is arranged to extend transversely of the end at the girth line, its length being determined' in eachinstance by the requirements of the particular case.l It is shaped to follow Vthe contour of the flange 5, to which it is secured by rivets 16a, and it also embraces the reinforcing elements 11- to which it is s e-4 cured by rivets 16". Its horizontal flange is secured to the web 4 by suitable fastenbe varied in length to suit the particular case, and may also be varied in weight as conditions require. It is inserted 'at the point where the endstructure is subjected to thegreatest stresses, yet at the same timel any necessary variations in its weight or length will not change .the end -clearance of the structure.

.rior thereof so as to 'form an This variable member combines with the shaped lower margin of thepupper panel to form. a very stiff ltransverse reinforcement, and 1t also coperates with the vertical reinforcing members 11 to form a central rein-4 forcement for both 'the lower and upper panels as it will resist horizontal end .transmit end thrust reactions to the side plates of Ythe car, and to receive the end the upper margin of the panel on the exteeffective weather closure.

From the foregoing .description it will be seen that my invention provides an end structure in .which all ofthe major portions requiring special forming, such as the upper and lower panels, may bejuniform for all applications ofthe end, yet thel'weight, of

the structure as a. wholemay ,bey varied asv required byvariationsjin'smaller parts, .such l. as the transverse. member 16, which vvariable y plate 19. Thev facia plate 2O extends across partis readily made frommat'erial commonly in stock infany repairshopA and which requires no tunusual forming. IOf course, the vertical `rnembersll `may 'be'varied if circumstances demand, vand they too, being of any of a variety of adaptable commercial shapes, may be easily fabricated'in .the repair shop. It will be seem-therefore, that' vthispend structureis one which permits of great economy because of the fact that while substantially all o f its partsare uniform for-all applications,it is susceptible of variation in certain of its minor members which will adapt it to any of'avwide'variety of requirements.

I am aware described and illustrated lmay be embodied in a variety. of forms not herein specifically mentioned, and .that the illustrative form herein disclosed is susceptible of modifications and Variations still within the scope of the invention, which is indicated in th'e followin claims.
